FIR Beam Line of MIRRORCLE‐20

The tabletop synchrotron MIRRORCLE‐20 has been optimized as an FIR beam source for the life science research. To collect the radiation from whole arc of the orbit, there is a magic mirror and a circular mirror installed within MIRRORCLE‐20. There is an FT‐IR and a cooled silicon bolometer for FIR. According to the specification of MIRRORCLE‐20, the e‐beam current is 100mA, the pulse width is 0.1msec, the peak storage current is 3A and the repetition is 100Hz. The power of MIR (wavelength shorter than 50μm) measured by thermopile is about 59mW and that of FIR (wavelength longer than 50μm) estimated by theoretical spectrum is about 8.5mW.
